SK Planet Commercializes Industrial Safety Management by Combining AI with DTS Fiber Optic Sensors

SK Planet has commercialized safety management solutions for various industrial sectors including chemical, oil refining, manufacturing, and railways by combining its self-developed AI with DTS (Distributed Temperature Sensor) technology. DTS is a technology that uses the fiber optic cable itself as a sensor, measuring real-time temperature at meter intervals across sections up to 50km in length.

How DTS Technology Works and Its Structure

DTS injects laser light into the fiber optic cable and measures the surrounding temperature by detecting changes in the speed of light due to variations in the refractive index. The system consists of a DTS Interrogator, optical cable sensor, SK Planet RB Insight, and AI Cloud. The interrogator analyzes data across sections up to 50km, RB Insight performs anomaly detection based on this data, and AI Cloud handles modeling and updates.

Key Commercial Use Cases

AI-based DTS technology overcomes the limitations of existing visual inspections or spot-based inspections, enabling real-time full-coverage inspection.

• Pipeline Leak Detection: Detects leaks and temperature anomalies in real time across complex pipelines at oil and gas plants to prevent accidents.
• Tunnel and Underground Utility Tunnel Fire Detection: Captures temperature changes at the meter level across long-distance infrastructure spanning several km to detect fires early.
• High-Heat Facility Monitoring: Precisely measures temperatures across different parts of ultra-high-heat structures, such as refractory materials in reactors or furnaces, to ensure safety.

Implications and Features

This solution contributes to maintaining the stability of large-scale facilities and preventing potential issues. It is also an eco-friendly technology that does not generate harmful radio waves or substances, and can be used to strengthen the competitiveness of national facilities and industrial complexes.
